Indexes for inflation taxable income brackets under New Jersey gross income tax.

This bill (A4427) would automatically adjust New Jersey's income tax brackets each year based on inflation, preventing "bracket creep" where inflation pushes taxpayers into higher tax brackets without real income growth. It directly affects all New Jersey residents who pay state income tax by ensuring the income thresholds for each tax rate rise with the cost of living. The key mechanism requires the state to annually update the taxable income levels in the tax tables using the Consumer Price Index (CPI), as specified in the proposed amendment to N.J.S.54A:2-1. This change would maintain the same tax burden for middle- and lower-income earners as prices increase, without altering the current tax rates.
